MJSONWP - Internal error running command: Error: ENOENT (Android - Python + Appium)

i´ve tried to run python test automation script using my own device (samsung note 2) with Appium server (v 1.7.2)

I¨ve installed: + python 2.7.14 + appium server 1.7.2 + python appium server

here´s my code:

 import os
 import unittest
 from appium import webdriver
 from time import sleep

 class AndroidTests(unittest.TestCase):
      "Class to run tests against Banco Galicia app"
      #print os.path.abspath(os.path.join(os.path.dirname(__file__)  
      def setUp(self):       
          "Setup for the test"
          desired_caps = {}
          desired_caps['platformName'] = 'Android'
          desired_caps['platformVersion'] = '4.4.2'
          desired_caps['deviceName'] = 'adf70dc728bcbf33'
          # Returns abs path relative to this file and not cwd
          desired_caps['app'] = os.path.abspath(os.path.join(os.path.dirname(__file__),'app-all_environment-debug_6_11_10.apk'))     
          desired_caps['appPackage'] = 'ar.com.galicia.app.all_environment'
          desired_caps['appActivity'] = 'ar.com.galicia.switcher.activities.SwitcherActivity'
          self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

      def tearDown(self):
          "Tear down the test"
          self.driver.quit()

      def test_homologacion(self):
          "Test HOMOLOGACION"
          element = self.driver.find_element_by_name("HOMOLOGACION")
          element.click()
          #self.driver.find_element_by_name("Single Player").click()
          #textfields = self.driver.find_elements_by_class_name("android.widget.TextView")
          #self.assertEqual('MATCH SETTINGS', textfields[0].text)

 #---START OF SCRIPT
 if __name__ == '__main__':
 suite = unittest.TestLoader().loadTestsFromTestCase(AndroidTests)
 unittest.TextTestRunner(verbosity=2).run(suite)
